3119668c0e drm/amd/display: avoid disable otg when dig was disabled
[Why]
This is a workaround for an dcn3.15 hang
that happens if otg dispclk is ramped while
otg is on and stream enc is off. But this
w/a should not trigger when we have a dig active.

[How]
Avoid disable otg when dig was disabled.

[Note]
Reapplying commit b07bb766b6 ("drm/amd/display: avoid disable otg when dig was disabled")
which was incorrectly reverted.

087bad7eb1 drm/amdgpu: fix enum odm_combine_mode mismatch
A conversion from 'bool' to 'enum odm_combine_mode' was incomplete,
and gcc warns about this with many instances of

display/dc/dml/dcn20/display_mode_vba_20.c:3899:44: warning: implicit conversion from 'enum <anonymous>' to 'enum
odm_combine_mode' [-Wenum-conversion]
 3899 |     locals->ODMCombineEnablePerState[i][k] = false;

Change the ones that we get a warning for, using the same numerical
values to leave the behavior unchanged.

56c121dcd5 dt-bindings: clock: qcom,msm8996-cbf: Describe the MSM8996 CBF clock controller
MSM8996 Core Bus Fabric (CBF) clock controller clocks an interconnect
between two CPU clusters. The CBF clock should follow the CPU
frequencies to provide enough bandwidth between clusters. Thus a single
driver implements both a clock and an interconnect to set the clock
rate.

0277263659 clk: qcom: add the driver for the MSM8996 APCS clocks
Add a simple driver handling the APCS clocks on MSM8996. For now it
supports just a single aux clock, linking GPLL0 to CPU and CBF clocks.

Note, there is little sense in registering sys_apcs_aux as a child of
gpll0. The PLL is always-on. And listing the gpll0 as a property of the
apcs would delay its probing until the GCC has been probed (while we
would like for the apcs to be probed as early as possible).

5dbfcd25a0 drm/amd/display: fix cursor offset on rotation 180
Cursor gets clipped off in the middle of the screen with hw rotation
180. Fix a miscalculation of cursor offset when it's placed near the
edges in the pipe split case.

Cursor bugs with hw rotation were reported on AMD issue tracker:
https://gitlab.freedesktop.org/drm/amd/-/issues/2247

The issues on rotation 270 was fixed by:
https://lore.kernel.org/amd-gfx/20221118125935.4013669-22-Brian.Chang@amd.com/
that partially addressed the rotation 180 too. So, this patch is the
final bits for rotation 180.

642f1b4052 drm/amd/display: fix read errors pertaining to dp_lttpr_status_show()
Currently, it is likely that we will read the relevant LTTPR caps after
link training has completed (which can cause garbage data to be read),
however according to the DP 2.0 spec that should be done before link
training has commenced. So, instead of reading the registers on demand,
use the values provided to us by DC.

faf6943146 arm64: dts: qcom: msm8916-thwc: Add initial device trees
This commit adds support for the ufi-001C and uf896 WiFi/LTE dongle made by
Tong Heng Wei Chuang based on MSM8916.
uf896 is another variant for the usb stick. The board design
differs by using different gpios for the keys and leds.

Note: The original firmware does not support 64-bit OS. It is necessary
to flash 64-bit TZ firmware to boot arm64.

Currently supported:
- All CPU cores
- Buttons
- LEDs
- Modem
- SDHC
- USB Device Mode
- UART

e047c5eaa7 kunit: Expose 'static stub' API to redirect functions
Add a simple way of redirecting calls to functions by including a
special prologue in the "real" function which checks to see if the
replacement function should be called (and, if so, calls it).

To redirect calls to a function, make the first (non-declaration) line
of the function:

	KUNIT_STATIC_STUB_REDIRECT(function_name, [function arguments]);

(This will compile away to nothing if KUnit is not enabled, otherwise it
will check if a redirection is active, call the replacement function,
and return. This check is protected by a static branch, so has very
little overhead when there are no KUnit tests running.)

Calls to the real function can be redirected to a replacement using:

	kunit_activate_static_stub(test, real_fn, replacement_fn);

The redirection will only affect calls made from within the kthread of
the current test, and will be automatically disabled when the test
completes. It can also be manually disabled with
kunit_deactivate_static_stub().

The 'example' KUnit test suite has a more complete example.

7170b7ed6a kunit: Add "hooks" to call into KUnit when it's built as a module
KUnit has several macros and functions intended for use from non-test
code. These hooks, currently the kunit_get_current_test() and
kunit_fail_current_test() macros, didn't work when CONFIG_KUNIT=m.

In order to support this case, the required functions and static data
need to be available unconditionally, even when KUnit itself is not
built-in. The new 'hooks.c' file is therefore always included, and has
both the static key required for kunit_get_current_test(), and a table
of function pointers in struct kunit_hooks_table. This is filled in with
the real implementations by kunit_install_hooks(), which is kept in
hooks-impl.h and called when the kunit module is loaded.

This can  be extended for future features which require similar
"hook" behaviour, such as static stubs, by simply adding new entries to
the struct, and the appropriate code to set them.

Fixed white-space errors during commit:

05d5562e40 Revert "drm/i915/hwmon: Enable PL1 power limit"
This reverts commit 0349c41b05.

0349c41b05 ("drm/i915/hwmon: Enable PL1 power limit") is incorrect and
caused a major regression on ATSM. The change enabled the PL1 power limit
but FW sets the default value of the PL1 limit to 0 which implies HW now
works at minimum power and therefore the lowest effective frequency. This
means all workloads now run slower resulting in even GuC FW load operations
timing out, rendering ATSM unusable.

A different solution to the original issue of the PL1 limit being disabled
on ATSM is needed but till that is developed, revert 0349c41b05.

Commit 3bc753c06d ("kbuild: treat char as always unsigned") broke
kprobes.  Setting a probe-point on 1 byte conditional jump can cause the
kernel to crash when the (signed) relative jump offset gets treated as
unsigned.

Fix by replacing the unsigned 'immediate.bytes' (plus a cast) with the
signed 'immediate.value' when assigning to the relative jump offset.

The workarounds/tuning settings should still be applied properly on PVC
even without the MCR annotation, but readback verification on
CONFIG_DRM_I915_DEBUG_GEM builds could potentitally give false positive
"workaround lost on load" warnings on parts fused such that a unicast
